Brock vs Punk I think could have been the best match to have as the WM 31 main event. Punk is pretty much the Anti-Brock in a way. He is the guy who showed up everday, he was the guy who worked all the ppvs. Plus the history with Heyman and their match at Summerslam. It could have been the best match for WM 31.

CM Punk has been gone from WWE so long it's impossible to tell. I think that match would have a lot more drawing power than Reigns vs. Lesner.

Nope.

It's hard to imagine WWE booking that, though, regardless of how well it would draw.

You were never getting Lesnar/Punk

Lesnar/Punk had an awesome match at Summerslam, but I don't think they would've built Wrestlemania around them. I could see him winding up with Rollins or Ambrose in a marquee match of some kind if he had stayed.

Nah, even though some people might have wanted to see it, I wouldn't have seen it happening.
